Linux kernel source tree

needs_teardown is a device flag that indicates when virtual queues need
to be recreated. This happens for certain configuration changes: queue
size and some specific features.
Currently, the needs_teardown state can be incorrectly reset by
subsequent .set_vq_num() calls. For example, for 1 rx VQ with size 512
and 1 tx VQ with size 256:
.set_vq_num(0, 512) -> sets needs_teardown to true (rx queue has a
non-default size)
.set_vq_num(1, 256) -> sets needs_teardown to false (tx queue has a
default size)
This change takes into account the previous value of the needs_teardown
flag when re-calculating it during VQ size configuration.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
